"In 1777, the British crown approved General John Burgoyne's plan to quash
American unrest by isolating New England, the hotbed of the rebellion, from
the other colonies. The attack called for three armies:
1) A large invasion force under Burgoyne would proceed south from Quebec
through the Champlain Valley
2) A second force under Col. Barry St. Leger would head east from Fort
Ontario(Oswego, N.Y.) to secure Fort Stanwix and the Mohawk Valley(N.Y.).
3) General William Howe's army would move up the Hudson Valley from New York
City to meet the other forces at Albany."
